Definitions
- the invention relates to a unit dose detergent for cleaning a coffee machine and to a method of cleaning such coffee machine by dissolving the unit dose detergent in the water tank thereof.
- Methods for cleaning coffee machines are known, for instance, such as disclosed in US patent No. 6,514,429.
- This patent describes the art, i.e. a cleaning method wherein the water tank is cleaned by applying a cleaning tablet.
- This patent discloses the use of a composition for use in a water tank wherein a base composition is in the form of a tablet, which evolves its function essentially following addition to a first filling of the water tank, and wherein one particle having a coreango comprising _a_ substance evolving its function substantially following emptying of the first filling from the water tank and inflow of fresh water to the same.
- the tablet has a covering surrounding the core and comprising a compound, whose solubility increases with decreasing concentration of H+ ion in the surrounding medium.
- the solubility of the compound increases with decreasing OH- ionic concentration and therefore decreasing pH value in the surrounding medium.
- Tablet ingredients comprise amidosulfuric acid, maleic acid, and sodium hydrogencarbonate.
- a particular suitable tablet contains sodium tripolyphosphate, sodium carbonate, sodium bicarbonate, trisodium NTA, sodium metasilicate, sodium sulfate, sodium dichloroisocyanurate, polymer, and nonionic surfactant.
- the compound may comprise a pH-sensitive polymer, which comprises at least one repeating unit having at least one basic function, which is not part of the polymer backbone chain, and which is preferably a secondary or tertiary amine.
- a pH-sensitive polymer which comprises at least one repeating unit having at least one basic function, which is not part of the polymer backbone chain, and which is preferably a secondary or tertiary amine.
- the invention pertains to a unit dose detergent for cleaning a coffee machine consisting of a water-soluble sachet filled with a composition
- a composition comprising: a) 10-40 wt.% of a sequestering agent; b) 15-50 wt.% of a persalt or peracid; c) 0.1-10 wt.% of a scale inhibitor selected from phosphonate and a carboxyl-functional polymer; d) a sufficient amount of an alkaline compound to obtain a pH of at least 10 when the composition is dissolved in water; and e) optionally, to a total of 100 wt.% of ingredients a) to e) of at least one auxiliary agent; wherein 30-100 wt.% of the total of a) to e) is in the form of granules having a mean particle size 250-800 ⁇ m, a BET specific surface area of less than 100 m 2 /g, and a dissolution rate of less than l""
- the invention resides in a unit dose detergent which is able to clean extremely fast and reliable.
- the sachet (or pouch) of the invention is suitable for quick cleaning cycles of food and beverage service applications where manual dosing of cleaning chemicals is desired. It does not dissolve during handling but dissolves quickly within 1 min, preferably within 45 sec, during the cleaning cycle. Cleaning cycles used in this area normally use very small quantities of water and the level of both pressure and agitation applied on this water is very low.
- the term "coffee machine” within the context of the present inventions includes machines for food and beverage service applications like hot and cold drink vending machines, particularly such as machines for making coffee, espresso, cappuccino, tea, chocolate, and the like.
- the composition comprising granules, or optionally a mixture of granules and powder, includes a persalt or peracid as ingredient which creates some degree of agitation of the cleaning solution by gas release without neutralization of the cleaning solution, thereby increasing the dissolution rate. Due to the presence of granular material in the composition, the active ingredients in--the sachet are made available in the cleaning solution almost as quickly as when a liquid detergent would have been used. It also provides complete cleaning in the same time as a liquid detergent without encountering all the problems which are associated with the use of liquid detergents.
- the sachet material is preferably cold water-soluble
- PVA polyvinyl alcohol
- Such sachets are known in the art.
- a detergent dispenser which comprises a powder detergent and a pouch or bag containing the powder detergent has been disclosed, wherein the pouch is made of a cold water- soluble polyvinyl alcohol derivative.
- the pouch is resistant to acid and to alkali and can retain its solubility over a long period of time.
- the pouch or bag contains a powder detergent which is capable of dissolving when it is placed into water.
- the powdery detergents described are inorganic components dispersed in a continuous phase comprising an organic component constituting the detergent composition.
- the organic component is a surfactant, usually an anionic or non- ionic surfactant, and the inorganic component is a powdery alkali.
- these powder detergents are intended for laundry and dishwashing and are unable to dissolve within 1 min and for that reason are unsuitable for cleaning coffee machines.
- the polyvinyl alcohols can be applied as a water-soluble polymer which is widely used for water-soluble films and in other fields.
- PVA which has a degree of saponification ranging from 80 to 95 mol % exhibits rapid water solubility.
- PVA which has a degree of saponification of at least 98 mol % is called and is less suitable since it dissolves in water when it is allowed to stand in the water for a long period of time or if it is placed into hot water.
- Preferred sequestering agents are -compounds--that have a strong complexation with or bonding to calcium and magnesium.
- Most preferred are sodium or potassium salts of NTA (nitrilotriacetic acid) , MGDA (methylglycine- diacetic acid) , EDTA (ethylenediamine tetraacetic acid) , and (S,S)-EDDS (ethylenediamine-N,N' -disuccinic acid), or mixtures thereof.
- Preferred amounts of the sequestering agent amount to 20-30 wt.%.
- Preferred persalts are percarbonate and perborate.
- the counter ion is an alkali metal such as sodium or potassium.
- Preferred peracids are sodium or potassium salts of phthalimidoperhexanoic acid (PAP) and peracetic acid (PAA) .
- Preferred amounts of the peroxy compound amount to 22-35 wt.%.
- Preferred scale inhibitors are phosphonates such as, sodium or potassium salts of ethanehydroxydiphosphonic acid and aminotrimethylenephosphonic acid, and carboxyl- functional polymers such as poly (meth) acrylic acid, and copolymers of (meth) acrylic acid and maleic acid or anhydride.
- the alkaline compound may be any compound that is able to bring the pH to at least 10. Suitable alkaline compounds include metasilicate, granulated or powder-like silicate, disilicate, sodium hydroxide, sodium carbonate, sodium hydrogencarbonate, and the like.
- the composition may further comprise auxiliary compounds to complete the composition to 100 wt.%. Suitable auxiliary compounds include phosphates (such as sodium tri (polyphosphate) , sodium pyrophosphate, and sodium orthophosphate) , sequestering agents other than those of a) , perfumes, colorants, fillers, emulsifiers and the like.
- the active ingredients in the composition are at- - ⁇ least partly granular and may be partly powder.
- the granular components are preferably NTA, sodium percarbonate and sodium metasilicate, but the other component may also be used in granular form.
- the amount of granular material should be in the range of 30 to 100 wt.%, preferably 40-90 wt.%, more preferably 60-80 wt.%.
- the granular material is material with a particle size ranging from 250 - 800 micron, preferably be about 300 - 750 micron, most preferably 350 - 500 micron.
- the BET specific surface area is less than 100 ⁇ 2 /g, preferably less than 90 m 2 /g, most preferably less than 80 m 2 /g.
- a suitable method for cleaning coffee machines is to dose the sachet containing the composition to the water tank (also known as brewer) and to add water. For instance, the brewer is charged with the sachet and 20 ml of water having a temperature of 90° C to 95° C. After a delay time of about 10 seconds to allow the sachet to dissolve at least partially, the brewer is filled by charging an additional amount of 80 ml of water of 90° C to 95° C. The sachet and granule/powder mixture quickly dissolve. The brewer stays filled with the cleaning solution for 40 seconds which allows complete dissolution and gives excellent brewer cleaning. The brewer is then discharged and flushed to remove all traces of detergent.
- the invention is further illustrated by the following non-limitative examples.
- a transparent cup was filled with water of 90° C.
- the sachet, powder or tablet was added and allowed to (partially) dissolve for 10 seconds.
- the water was agitated using a stirrer for 3 seconds (which simulates the filling of the system) .
- the time was measured to dissolve all the material of sachet, powder or tablet.
- compositions were used: Sachet filled with granular material: sodium tri (polyphosphate) 10 wt.% powder sodium NTA 24 wt.% granules sodium percarbonate 30 wt.% granules sodium metasilicate 14 wt.% granules sodium carbonate 17 wt.% powder tetrasodium acetodiphosphonate 5 wt . % powder
- All granular constituents had a particle size within the range 250 - 500 ⁇ m.
- Sachet filled with powder sodium tri (polyphosphate) 10 wt.% powder sodium NTA 24 wt.% powder sodium percarbonate 30 wt.% powder sodium metasilicate 14 wt.% powder sodium carbonate 17 wt.% powder tetrasodium acetodiphosphonate 5 wt . % powder
- All powder constituents had a particle size ⁇ 180 ⁇ m.
- Tablet The same composition as used for the powder was used and compacted to a tablet under a pressure of 8.107 N/m 2 .
